Ubuntu Servers :: "perldoc Net::FTP" Following Documentation But Dont Understand

I'm setting up backuppc for backing up over ftp. I have been following this guide: [URL].. The difference is I need to use FTP to backup as opposed to ssh / rsync.I have followed the guide and instead of using

Code:
$Conf{XferMethod} = 'rsync';
I am using
Code:
$Conf{XferMethod} = 'ftp';
as per: http://backuppc.sourceforge.net/faq/BackupPC.html

For linux/unix machines you should not backup "/proc". This directory contains a variety of files that look like regular files but they are special files that don't need to be backed up (eg: /proc/kcore is a regular file that contains physical memory). See $Conf{BackupFilesExclude}. It is safe to back up /dev since it contains mostly character-special and block-special files, which are correctly handed by BackupPC (eg: backing up /dev/hda5 just saves the block-special file information, not the contents of the disk).

Alternatively, rather than backup all the file systems as a single share ("/"), it is easier to restore a single file system if you backup each file system separately. To do this you should list each file system mount point in $Conf{TarShareName} or $Conf{RsyncShareName}, and add the --one-file-system option to $Conf{TarClientCmd} or $Conf{RsyncArgs}. In this case there is no need to exclude /proc explicitly since it looks like a different file system.

Next you should decide whether to run tar over ssh, rsh or nfs. Ssh is the preferred method. Rsh is not secure and therefore not recommended. Nfs will work, but you need to make sure that the BackupPC user (running on the server) has sufficient permissions to read all the files below the nfs mount.

Ssh allows BackupPC to run as a privileged user on the client (eg: root), since it needs sufficient permissions to read all the backup files. Ssh is setup so that BackupPC on the server (an otherwise low privileged user) can ssh as root on the client, without being prompted for a password. There are two common versions of ssh: v1 and v2. Here are some instructions for one way to setup ssh. (Check which version of SSH you have by typing "ssh" or "man ssh".) Everything seems to be working correctly except when a backup is executed I get this:
